Configure the CData JDBC Driver for Epicor ERP in a Connection Pool in Tomcat

Connect to Epicor ERP data from a connection pool in Tomcat.

The CData JDBC Drivers support standard JDBC interfaces to integrate with Web applications running on the JVM. This article details how to connect to Epicor ERP data from a connection pool in Tomcat.

Connect to Epicor ERP Data through a Connection Pool in Tomcat

  1. Copy the CData JAR and CData .lic file to $CATALINA_HOME/lib. The CData JAR is located in the lib subfolder of the installation directory.
  2. Add a definition of the resource to the context. Specify the JDBC URL here.

    To successfully connect to your ERP instance, you must specify the following connection properties:

    • Url:the URL of the server hosting your ERP instance. For example, https://myserver.EpicorSaaS.com
    • ERPInstance: the name of your ERP instance.
    • User: the username of your account.
    • Password: the password of your account.
    • Service: the service you want to retrieve data from. For example, BaqSvc.

    In addition, you may also set the optional connection properties:

    • ApiKey: An optional key that may be required for connection to some services depending on your account configuration.
    • ApiVersion: Defaults to v1. May be set to v2 to use the newer Epicor API.
    • Company: Required if you set the ApiVersion to v2.

    Built-in Connection String Designer

    For assistance in constructing the JDBC URL, use the connection string designer built into the Epicor ERP JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

    java -jar cdata.jdbc.epicorerp.jar

    Fill in the connection properties and copy the connection string to the clipboard.

    You can see the JDBC URL specified in the resource definition below.

    <Resource name="jdbc/epicorerp" auth="Container" type="javax.sql.DataSource" driverClassName="cdata.jdbc.epicorerp.EpicorERPDriver" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" url="jdbc:epicorerp:ervice=Erp.BO.CustomerSvc;ERPInstance=MyInstance;URL=https://myaccount.epicorsaas.com;User=username;Password=password;InitiateOAuth=GETANDREFRESH" maxActive="20" maxIdle="10" maxWait="-1" />

    To allow a single application to access Epicor ERP data, add the code above to the context.xml in the application's META-INF directory.

    For a shared resource configuration, add the code above to the context.xml located in $CATALINA_BASE/conf. A shared resource configuration provides connectivity to Epicor ERP for all applications.

  3. Add a reference to the resource to the web.xml for the application. Epicor ERP data JSP jdbc/EpicorERP javax.sql.DataSource Container
  4. Initialize connections from the connection pool: Context initContext = new InitialContext(); Context envContext = (Context)initContext.lookup("java:/comp/env"); DataSource ds = (DataSource)envContext.lookup("jdbc/EpicorERP"); Connection conn = ds.getConnection();
